IMPROVEMENT IN GAS-MIXING MACHINES.

Specification forming part of Letters Patent No. 170,677, dated December 7, 1875; application tiled June 1S, 1874.l

To all whom it may concern:

Beit known that I, LoUIs LAEszwEERT, of the city and county of San Francisco, State of California, have invented an Improvement in Gas-Mixing Machines, of which the following is a specification:

My invention relates to au improved apparatus for the apportioning of gases' that are to be mixed together, with devices for the more intimately mixing and purifying them previous to their combustion; the apportioning being effected by an arrangement of inlets aftlxed in certain definite positions onto casings in which gas-drums are made to reyvolve by the inowing gas'es and auxiliary clock-work; the positions of these inlets regulating the heights of the contained Water and remaiiiingA gas volumes; the purification being performed by forcing these apportioned gases through cylinders fitted with chloride of calcium and charcoal, or their equivalents, and the mixing by thoroughly stirring up these apportioned and purified gases by means of a fan kept revolving at a high speed iu a separate chamber actuated by the same clockwork that operates the drums.

Figure lis a vertical longitudinal elevation of the improved gas-mixer embodying my invention, parts being broken away ot' the apparatus to exhibit the interior construction. Fig. 2 is a vertical transverse section of Fig. l through the line c c. Fig. 3 is a vertical 1ongitudinal section of the governor with lamp attachments. Fig. 4 is a sectional plan ot' the purifying and mixing chambers.

My invention refers more particularly to the apportioning of certain gases, which, when puried and thoroughly combined togethel,

and made to undergo combustion, produce such heat as to render a Wire platina burner, or any other incombustible or infusible material, properly arranged and adjusted to the ame, incandescent and ot' great illuminative power.

These gasesmay be ordinary coal-gas and air, or pure oxygen and ordinary coal-gas, or the protoxide or deutoxide of azote with some other form of hydrocarbon; the main features of this invention being to regulate the proportionswith which such gases are to be mixed together, and their purity, so as to insure their greatest efficiency for illuminating and heating purposesfwithout incurring any danger in making explosive compounds.

As an example, for the sake ot' convenience,

the gases supposed to be employed for this apparatus are ordinary coal-gas and common atmospheric air, in the proportions of one of the former to two of the latter, such mixture being admirably adapted for burning on an open wire-work platina burner, and is free ,from danger. y

In order to effect this, I place iu separate cylindrical gas-tight casings two gas-drums, side by side, with their central shafts in con- -nection with one another, and affix a system of clock-work, or other suitable auxiliary power, onto the stands holding these casings, in such manner that it shall engage these shafts, and cause these drums to revolve iu a positive direction; one drum receiving by inhalation its supply of air through an open pipe, and the other its supply of coal-gas from l anpgrdinary gas-meter. The contents of each of these drums are discharged into small cylinders iilled with chloride of calcium and car bon, or their equivalents, so that they may be desiccated and purified in their passage to a mixing-chamber, wherein a fan is kept revolving at a high rate of speed actuated also by clock-Work. p

The mixture thus perfected in this chamber ows through a large pipe to a governor, which is a vessel wherein the pressure ot' the combined gases can be regulated by the adjustment of Weights previous to these gases being finally forced to a suitable vehicle for combustion. Onto these casings,

which are iitted with revolving drums, severall small inlets with stoppers vare so arranged in certain denite positions that water can be poured into them according to the quantity required, so as to obtain certain determined proportions between the remaining gas capacity of each drum. Thus equal parts of gas and air may be made to lill these remaining spaces, and be discharged as explained, or the proportion of one ofgas to two, three, or

n' noce-v four, &c., of ai-r, or one, two, three, Snc., of gas to other quantities of air, may be regulated and 4readily determined.

With reference to the iigures in the drawing, G C are the casings, and D Dl are the gas-drums, which are fitted within them so as to have their central shafts or axes S S' re spectively, on which they revolve, in gastight boxes, communicating with; each other by the gearing U c in such manner that, on motion being communicated to one, the other will follow at Ythe same rate of speed. For assisting in actuating these drums, regulating their movements, and mixing the gases, which pass through them, a system of clock-work, W W', p, E, e e', is attached to the castiron stand I I, which hold-s the-v casings G C. This clock-work consists, essentially, of loose and tixed tooth-wheels W W' respectively, which gear into one another and engage a pinion, p, ixed to the spindle s of the drum D.

A ratchet-wheel, e, actuates the wheel W by the ixed pawl w, when a spring contained within the drum E attached to this ratchetwheel is wound up to a sufticient tension by the handle H, while acord'from this drum E to a roller, e', winds up and unwinds, so as to regulate the movements.

M is an ordinary coal-gas meter, supplied by a pipe, R, which conveys this gas to the drum D by a pipe, It', which enters the casing G near the center, and is bent upward for a considerable distance into the space provided in theY drum D, so as to reach above all levels of the water contained, and so that each of its four or more compartments shall receive and deliver its gas contents through slits arranged in the same manner as in the gas-meter M. A

The drum D in the case C" receives air from the pipe R2 by inhalation, and discharges the contents of its compartments in the same :manner as the drum D, the one passing through the pipe Z and the other through the pipe Z, fixed to`the top of the casings C C respectively. Each gas in escaping is forced to enter perforated cylinders d d', filled with chloride of calcium and charcoal, or their l equivalents. These cylinders are closed at one end, and are made adjustable by screwing into pipes r r', fixed at right angles to the i pipes Z Z.

Xis the mixing-chamber, into which the pipes 1' r discharge on opposite sides, so that after the gases have passed through the chloride ofcalcium and carbon compound,

' they may enter the chamber simultaneously.

In this compartment X a fan, F,A provided with several blades, is kept revolving at a high speed by the multiplying-gearing hh h, connecting with the. beveled wheels b b by the spindle t, and by the spindle with the clock-work W W p e e', which actuates the drums D D. In this compartment the gases are thoroughlyand intimately mixed, so that combination may be increased, as, in practice, the color of the light in such illuminating mixtures depends a great deal on the perfection of the combination formed.

lifting up avhollow ball-valve, q, which serves to prevent any back action, and pass through the opening O into the pipes w w', and thence into the governor G, wherein the necessary pressure of the mixed gases is regulated by weights m m', and, by this arrangement, is

made to descend in a continuous stream 'through the pipe a, and' upward again to the lamp L and burner B.

For the apportioning of such gases, inlets to, are provided respectively on the upper `mined positions, so that when a liquid is poured through them into these casings to the and their deliveries shall bear a certain relative proportion to one another, for, if a liquid "ll l1 l1 respectively, so that the gas-volume that may be delivered from the drum D shall be double that from the drum D, then, by pouring more liquid into the inlet Q of the whereas, if tlie'level Z2 be attained in the casing C, and that in C remain at l Z1, as at rst, the gas capacities and deliveries of the drums proportions as may be desirable, the different levels Z111 l2 l2 L3 Z3, &c., indicated by the inletsP P Pll in the casing C, giving to the retive fractional proportions of one another, and as the casing C is similarly arranged,

WhatI claim as my invention, and for which l am desirous of obtaining Letters Patentot :the United States, is- '1.
